90361749 divided by 677 
The aim is to understand the frequency of 677 in 90361749.

Going ahead to step 1:
The number 677 fits into 9 0 times, leaving a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 677

Going ahead to step 2:
677 can be fit into 90 0 times, resulting in a remainder of 90.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 90, we get 90.
Bring next digit (3) of the dividend behind the 90 and repeat the process: 903 / 677

Going ahead to step 3:
677 can be fit into 903 1 times, resulting in a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 677 from 903 to get 226.
Take the next digit (6) from the dividend and append it to 226, then repeat: 2266 / 677

Let's proceed to step 4:
When dividing 2266 by 677, we get 3 with a remainder of 235.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Subtracting 2031 from 2266 leaves us with 235.
Take the next digit (1) from the dividend and append it to 235, then repeat: 2351 / 677

Advancing to step 5:
677 goes into 2351 3 times with a remainder of 320.
The number 3 becomes the next digit in our result. 
Result so far: 133.0
Deduct 2031 from 2351 and we're left with 320.
Grab the next digit (7) from the dividend, add it to 320, then carry on: 3207 / 677

Going ahead to step 6:
When dividing 3207 by 677, we get 4 with a remainder of 499.
Put 4 as the next digit of the answer. 
Result so far: 1334.0
Subtract 2708 from 3207 to get 499.
Fetch the next digit (4) from the dividend, attach it to 499 and continue: 4994 / 677

On to step 7:
677 goes into 4994 7 times with a remainder of 255.
The number 7 becomes the next digit in our result. 
Result so far: 13347.0
The remainder is 255 after subtracting 4739 from 4994.
Take the next digit (9) from the dividend and append it to 255, then repeat: 2559 / 677

Going ahead to step 8:
The number 677 fits into 2559 3 times, leaving a remainder of 528.
Write down 3 as next digit of the result. 
Result so far: 133473.0
Deduct 2031 from 2559 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 9:
The number 677 fits into 5280 7 times, leaving a remainder of 541.
The next digit of our result is 7. 
Result so far: 133473.7
If we subtract 4739 from 5280, we get 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Let's proceed to step 10:
If we divide 5410 by 677, we get 7 and a remainder of 671.
Record the quotient 7 as the next digit in the result. 
Result so far: 133473.77
Deduct 4739 from 5410 and we're left with 671.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6710, and continue the process.

After the division, we end up with 133473.77 and a remainder of 0.671.
